AN IMPROVED ARRANGEMENT FOR THE PROGRESSIVE WAVE ABSORBER

S.W. Twu, C.C. Liu

Abstract

The progressive wave absorber discussed here in this paper contains several porous plates with different porosity. Four arrangements of progressive wave absorbers were compared in wave absorption. The results indicate that of the four arrangements examined, Arrangement 4 is the most effective at absorbing waves, for a relative water depth ranging from 0.05 to 0.5. The results also show that an eight-plate wave absorber is more effective than a six-plate wave, absorber. When waves are well within the relative water depth ranging from 0.05 to 0.5, reducing the G value of the rear plates further may provide even greater wave absorption efficiency .
